分析室外水泥混凝土地面起砂起灰的原因，不外乎以下幾點(diǎn)：
1、原材料不合格：室外水泥混凝土地面施工時(shí)，水泥存放時(shí)間過長(zhǎng)，有的甚至超過了3個(gè)月受潮結(jié)塊；在工地不同水泥混合使用，影響地面強(qiáng)度及耐磨性能；砂粒度過細(xì)，含泥量超過5%，這樣會(huì)增加拌合物的泌水性，影響水泥與骨料的黏結(jié)強(qiáng)度，導(dǎo)致施工好的室外水泥混凝土地面起砂起灰。
2、水灰比大：室外地面面層抹完后在表面有一層浮漿，浮漿與顆粒之間結(jié)合力差，強(qiáng)度低，有些工人為了趕時(shí)間就采取撒干水泥吸水的做法，凝結(jié)后的純水泥漿與下層不黏結(jié)，使室外水泥混凝土地面容易脫層起殼。
3、早期受凍：由于地面面積大，在冬季施工如無防凍措施，保養(yǎng)又不當(dāng)，使室外水泥混凝土地面早期受凍，輕者降低表面砂漿強(qiáng)度發(fā)生脫皮、起砂、乏沙，重者連混凝土基層也凍壞。
4、混凝土強(qiáng)度低：混凝土面層所用骨料無級(jí)配、含泥量大、北京中興盛達(dá)科技環(huán)保有限公司以**的價(jià)格、最誠(chéng)懇的態(tài)度、***的技術(shù)、最環(huán)保的藥劑，所以中興盛達(dá)科技環(huán)保有限公司是您**的選擇！
此方法處理起灰、起沙地面成本較低，但是對(duì)原地面外觀（顏色和表面形態(tài)）沒有改變。適用于對(duì)地面表觀效果要求不高、僅需解決起灰起沙地面硬化、防塵問題的客戶購(gòu)買材料、自行施工。
一、適用地面：
1、起灰、起砂的水泥砂漿地面硬化、防塵處理
2、起灰、起砂的混凝土地面或水泥混凝土路面硬化、防塵處理
3、起灰的水磨石地面硬化、防塵處理
4、起灰的水泥基骨料耐磨地面硬化、防塵處理
5、起灰的水泥基自流平地面硬化、防塵處理
二、施工步驟：?jiǎn)螇K施工周期一般為1-2天
1、基面要求及預(yù)處理：
①保證地面完全干燥，清掃地面砂塵，若表面有油漆、膠水、涂料等附著物，應(yīng)完全去除。
②已被油脂類物質(zhì)嚴(yán)重污染的地面不適用于本產(chǎn)品。
2、科地福KD600水泥地面起砂處理劑1號(hào)料（**天）：Analysis outdoor concrete floor from gray sand from reason, nothing more than the following:
1, the raw material failure: outdoor concrete floor construction, cement stored for too long, some even more than the three-month moisture caking; cement mix different sites, the impact strength and wear resistance surface; fine sand to spend, clay content exceeds 5%, this will increase the bleeding of mixing things, affect bond strength cement and aggregate, leading to the construction of good outdoor concrete floor from ash from the sand.
2, large water-cement ratio: outdoor ground surface after wiping the surface with a layer of floating pulp, the binding force between particles floating pulp and poor, low intensity, some workers in a hurry to take sprinkle dry cement water practices, after condensation The pure mud and not the underlying bond, the outdoor concrete floor easily delaminated from the shell.
3, early frost: Due to the large surface area, in the winter without freezing measures such as the construction, maintenance and not when, the outdoor concrete floor early frost, the light reduces the occurrence of surface peeling strength of mortar, sand, lack of sand, even in serious cases concrete base also frozen.
4, low strength concrete: Concrete surface layer with no graded aggregate, containing a large quantity of mud, Environmental Science and Technology Co., Ltd. Beijing Zhongxing Shengda at the lowest price, the most sincere attitude, the most professional technology, the most environmentally-friendly agent, so ZTE Shengda Technology Environmental Protection Co., Ltd. is your best choice!
This method for processing from gray, sandy ground from a low cost, but the original ground appearance (color and surface morphology) has not changed. Suitable for less demanding apparent effect on the ground, just settled the gray sand from the ground hardening, customers purchase materials and dust problems, self-construction.
A suitable ground:
1, from the gray, sand hardened cement mortar floor, dust treatment
2, from the ashes, sand or concrete floor hardened cement concrete pavement, dust treatment
3, from the gray terrazzo floor hardening, dust treatment
4, from the gray cement-based aggregate wear-resistant surface hardening, dust treatment
5, from the gray cement-based self-leveling floor hardening, dust treatment
Second, the construction step: a single block construction cycle is generally 1-2 days
1, the base surface requirements and pretreatment:
① ensure that the ground is completely dry, sand and dust sweeping the ground, if the surface paint, glue, paint and other attachments, should be completely removed.
② oil substances have been polluting the ground is not available for this product.
2. Branch to Fu KD600 concrete floor from the sand material agent on the 1st (first day):
